CONTROLLING MECHANISM FOR THE CARRIAGES OF TYPE-WRITING MACHINES.'

Specification of Letters Patent. v Patented Jan. 31, 1911.

Application led anuary 9, 1907. Serial No. 351,461.

le i 4known that I, JEROME B. Simon, a citizen of the. United States,lresiding at Derby, New Haven county, `Connecticut,

have invented certain new and useful Improveniente in ControllingMechanism for the Carriages of Type-Writing Machines, of which thefollowing is a specification.

My invention relates to means for enabling the ready-control of thecarriages of typeivriting\machines, i referably by mechanism adjacent tothe ey-board, for stop ping their; in either or both directions of theirmovement-#Whether to limit their point of starting or their point(if-stopping#- so that for example, the operator may readily change thelength oi` the position of beginning or endingof the line of writing.'

To this end, m'y invention comprises 4margin stops on the carriage,adjustable in the direction ofthe cai'riage movement and preferablyplural in number at both ends ofthe carriage, and a stop or stopscarried by the machine frame and controlled by a key or keys adjacent tothe key-board of the inavchine to be brought readily intovor out of en'-gagen'ient with said stops or certain of them.

Preferably, 'as'shoivn in the drawings accompanying and forming part ofthis speciiicatioii, a single stop on the mac ine frame, cont-rolled bya rocking,` two-keyed shaft,

`may be placed in either of two positions-in one of which' it engages,in each direction of movement oi the carriage, a marginal stop forlimiting the length of the printing line' to less than normal and in theother of which it engages in each direction of movement of the carriagea marginal stop for the norma-l line length. v Insaid drawings I haveillustrated only so much ofa ltypewriting ma-' chinees is necessary foran understanding of the invention, and-it will be understood that theinvention maybe a plied to various formsof typewriting machines and thatthe application to the form-here shown is merely illustrative. V

Figure 1 is a plan view of parts of the carriage-contr`olling mechanismof a typewrit- 6, fixed to and ing machine. Fig. 2 is aufroynt elevationofparts of said mechanism. Fig. 3 is a sectional elevation,` 4lookingfrom the righthand side ofthe machine, of theparts'shown in Figs. `1 and2. Fig. 4 is a plan View of the controlling rock-shaft and its keys.. -Q4 Parts of the stationary frame of themachine are indicated at 1. j ,r

At 2 shown one of the guide rails fixed to the machine frame and groovedlongitudinally mits-upper surface to receive the balls 3 Whereon the,4carriage travels.-

" 4. is the marginal-stop rack-bar, having for the greater part of itslengththe notched or toothed upper surface for locatingand holding themarginal stops at desired jpositions. .In the instance here shown, italso constitutes one of the carriage supporting and guiding rails, beingfastened atits ends to the end frame of the carriage (n ot shown) andltraveling on the balls 3, Whereon it is held and guided by one or morerolls or wheels '5, joiirnaled to bracket onbrackets projecting uprointhe rail 2 (see Fig. 3). Adjustable upon the toothed 'bar 4 are twoor more sets oi:' m rgin `stops, one set?, S, serving toregulate theextreme transverse carriage movement .tor maximum predetermined lengthof line, and the other set 9, 10, serving to arrest the carriage ineither or both directions of movement,

optionallyat points short of the `extreme predetermined line length.'Arranged upon tlie stationary frame of the machine, as or example, uponthe rail 2, is a stop 11, which in its normal position will make contactwith the terminal margin, stops 7, 8, whose bills for that purposeextend down from the carriage rail 4, substantially tothe level. of

the rail 2 on the main frame, but are adjustable to an elevated positionto 4engage'- the shorter bills of the intermediate para-.

graphing vor insetting stops 9, 10, as shown in dotted lines in. Fig. 2.Forthe purpose adjusting the stop 11, itV may, as here-shown, be carriedupon the inner end of an .arm-12.,

fpivoted at 1 3 to the rail 2,-the stop 11 being'4 so arranged as tooccupy the center of mo,-

enoug tion of the carriage so as to allow the limiting of the linelength on each side to any desired extent.

. The inner end of the arm 12'has a jaw engaging1 a stop screw 14, thejaw being highl the stop from the position shown in the full lines tothat shown in the dotted lines in Fig. 2. For actuating the stop the arm12 may have va projection `15 engaged onits upper and lower sidesrespectively by ajaw formed of the lever arm 16 and spring arni 17fastened by pin 19 to lever 18, Which is' pivoted at 19'1'to the rail 2and actuated 'by a rocking arm 20 engaging by an anti-fric tion roller20?- on a pin 20b at its upper end in a cam slot 21 in the right han'dend of lever 1S. The purpose of having arm 17 as a spring arm is topress the jaw of arm 12 by means of projection 15 yieldingly againststop screw 14, which aidsthe softness of the touch when key 26 isoperated, and causes stop 11 toyield when stop 9 passes it from theright to the left, and stop 10 from the left to the right. A. spring 22fixed to the 'machine frame and engaging apin 23 ou the arm 20, holdsthe latter in either-extreme p0 sition. The arm '20 is fixed to the rearend of the rock shaft 24 (see Figs.` 3 ande) which is mounteduponthemachine frameand projects forward, as shown, through the front plateofthe machine Where itis pro vided preferably With two keys 25, 26 onopposite sides of-its axis and serving -to'rock it in either direction.It will be seen that when the key 25, marked Out is pressed down, thevertical arm A20 is thrown to the left,ioscillating the 'lever 18andplacing the stopl 11` in the position-shownin lfull'lines,

Wheresit will' engage only the terminal stop 7,18; 1ut when thekey 26,marked In is presseddoyvn, the armQO-'moving-in the opposite-direct1on,f wil1 'throwthe stop 11 up to the position-shown indottedlines, whereat'itwill engage'the intermediate lstops 9,

.1Q; By adjusting-the terminal and .intermediate stops 'to the extremeline, length and to the intermediate paragraphing or insetting lengths'of line, and then operating'the Vkeys 25, 26, itfwill be lseen that'.the line length can be changed during the operation lof the machine'directlyfrom the key-board and`A to any', desired extent. and with anyrequired frequency? The intermediate, orone of the terminal; stops, mayas4 shown, also' carryv the 'bell tripping and'line lock arm 2;

I The'relation of this to the carriage operating and controllingmechanism-is .indicated in` Eig, 1, where I have shown vat 28 certain ofthemechan'i'sm for operating the'belland propelling the"ca'rriage, whichhowever are not here described this invention;-

bills of all of the margin stops are inclined tomovel over the stop 11onl return of the carriage to position beyond them from either.direction. To hold the stops 7, 8, 9,

10, to position upon the bar 4, it .has, as shown, teeth in its uppersurface, and with these' teeth engage the down-turned lips'29 on pivotedplates 30 hinged to each stop at- 31 and forced'down by spring 32, orlifted Having thusdescribed my invention, the followingis -What I claimas newr therein and Wish to, secure by Letters Patent:`
